1. A Gill Filament EROD Assay : Development and Application in Environmental Monitoring
Abstract : A gill filament-based assay for the cytochrome P450 1A (CYP1A)-catalysed activity ethoxyresorufin O-deethylase (EROD) was developed in rainbow trout (Oncorhynchus mykiss) and applied to Atlantic salmon (Salmo salar), Arctic charr (Salvelinus alpinus), Atlantic cod (Gadus morhua), saithe (Pollachius virens), and spotted wolffish (Anarhichas minor). Exposure to waterborne β-naphthoflavone (βNF; 10-6 M) induced branchial EROD activity in all species but the spotted wolffish. READ MORE

2. Basal and Pollutant-induced Expression of CYP1A, 1B and 1C isoforms in Fish : Implications for Biomonitoring
Abstract : Aquatic wildlife are exposed to contaminants in their natural habitats, and toxic pollutants may induce toxicity in sensitive target tissues and cells. There is therefore a need to establish biomarkers to determine exposure to certain classes of contaminants and the subsequent biological responses. READ MORE

3. Sol-gel Synthesis and Photocatalytic Characterization of Immobilized TiO2 Films
Abstract : Contamination of surface and ground water from industrial wastes and anthropogenic activities represents one of the greatest challenges to the sustainable development of human society. Heterogeneous photocatalysis, a kind of advanced oxidation process characterized by the production of highly oxidative hydroxyl radicals, is a relatively novel subject with tremendous potential in water treatment applications.

4. Synthesis of indolocarbazoles, bisindoles and related sulfur containing systems
Abstract : This thesis is focussed mainly on the synthesis and reactions of various indolocarbazoles, bisindoles and related sulfur containing systems, all possessing structural features present in many biologically active, natural or synthetic compounds. In the first part, synthetic routes towards the planar, pentacyclic ring systems of indolo[2,3-c]earbazole and indolo[3,2-a]carbazole are described. READ MORE

5. Gill EROD Activity in Fish : A Biomarker for Waterborne Ah-receptor Agonists
Abstract : Induction of the cytochrome P450(CYP)1A protein and the connected increase in 7-ethoxyresorufin O-deethylase (EROD) activity are common biomarkers in fish. Enhanced activity of this protein signals exposure to Ah-receptor agonists such as chlorinated dioxins, co-planar polychlorinated biphenyls (PCBs) and certain polycyclic aromatic hydrocarbons (PAHs).
